Preface: The laboratory gives you the opportunity to "get your hands on biology". You go beyond reading and study and actually enter into the process of doing science. The benefit you derive from the laboratory is directly dependent on two things: first, the care with which you perform the experiments and record your observations and, second, your awareness of the relationship between your observations and the general principles under study. Because of time limitations, we cannot investigate in the slow, methodical (often tedious) way scientist do. However, you will have the opportunity to measure, experiment, observe, and discover for yourself. In general, each laboratory exercise consists of the following: Safety box: alerts you to any hazardous materials -- Objectives: explicitly state what you can expect to accomplish -- Introduction: consist of background information to orient you to the biological concept being explored -- Preview: is a general overview of what you will be doing -- Procedure: provides step-by-step instruction to guide you through the laboratory exercise.--End-of-exercise questions: helps you focus on the important observations and concepts relevant to the day's investigation.
